2.5mm or 3.5mm

 2.5mm head set.

coz
1. a phone should have a headset adapter for speaker and mic.
2. blue tooth adapters are costly ($40 ) and 2.5mm headsets are $2 in India
( please focus on the relative cost, I am sure its the same elsewhere).
3. its extremely easy to make a 2.5mm to 3.5mm adapter. but impossible to
get the mic signal out if its a 3.5mm jack. a 3.5mm headset jack with mic is
not standard

Thanks

PS: I cannot get rid of this pesky warm feeling every time I see Openmoko
out do themselves with all this openness nonsense, common, be a man and just
take some random decisions will you (tongue in cheek).
